The ending of the UK LOM is a good example of a 'not explaining it all' ending.
Agreed, as much as I enjoy A2A, the ending to the UK LoM is perfect. It doesn't explain it all to you and leave a lot open for interpretation, but over all it is an extremely satisfying ending. I had always hoped Lost would kind of go that path and leave a lot of mysteries a bit vague.
